Abstract

There is provided a program execution device capable of improving user-friendliness by preventing that an application cannot be used when the application (program) being executed has abnormally terminated. An MA management unit (1205f) includes: an MA management unit main (2101) for receiving an instruction from an initialization sub-program and controlling the other constituent elements in the MA management unit (1205f); an XAIT acquisition analysis unit (2102) for analyzing the XAIT transmitted from the head end; an MA selection unit A (2103) for selecting a program to be started according to the XAIT analysis result; an MA start unit (2104) for starting the program specified; an MA monitoring unit (2105) for monitoring the operation condition of the program specified and notifying when an abnormal termination has occurred; and an MA selection unit B (2106) for selecting an alternative program.
